The disclosed invention is a composition for and a method of treating a Flaviviridae (including BVDV and HCV), Orthomyxoviridae (including Influenza A and B) or Paramyxoviridae (including RSV) infection, or conditions related to abnormal cellular proliferation, in a host, including animals, and especially humans, using a nucleoside of general formula (I)-(XXIII) or its pharmaceutically acceptable salt or prodrug.
This invention also provides an effective process to quantify the viral load, and in particular BVDV, HCV or West Nile Virus load, in a host, using real-time polymerase chain reaction (“RT-PCR”). Additionally, the invention discloses probe molecules that can fluoresce proportionally to the amount of virus present in a sample.

Highly efficient and practical methodology for the syntheses of D- and l-4,5-O-isopropylidene-2-cyclopentenone (9 and 22), versatile intermediates for the synthesis of carbocyclicnucleosides, have been developed via a ring-closing metathesis reaction from d-ribose in eight steps. The utility of D- and l-4,5-O-isopropylidene-2-cyclopentenone is demonstrated by their application for the preparation

We herein report the hitherto unknown synthesis of 3-deazacarbovir and its adenosine analogue. The major highlight in the synthesis of adenosine analogs is to use 6-N,N-diboc protected 3-deazapurines 9 and 11 for regioselective Mitsunobu coupling as well as unexplored palladium catalyzed coupling with these substrates. Synthesis of 3-deazacarbovir 1 has been accomplished by the regioselective palladium

An effective and practical synthesis of carbocyclic D- and L-6-azapyrimidine nucleosides (38) was described. Starting from D-ribose, a new efficient methodology for the synthesis of L-2,3-O-cyclohexylidene-4-cyclopentenone (23) was developed via a ring-closing metathesis, which was applied for the synthesis of L-cyclopentyl-6-azapyrimidine nucleosides (68). The regiospecific introduction of 6-azauracil
